Stamped + Klaviyo’s New Email Marketing Playbook: What’s Inside?

Introduction

Most DTC brands treat email marketing as a volume game—send more emails, get more sales. But what if we told you the brands winning at retention are actually sending fewer emails with dramatically better results?

The secret isn't frequency. It's precision.

While most brands blast generic promotions hoping something sticks, the smartest DTC companies have cracked the code on behavioral triggers. They know exactly when a customer is ready to replenish their last order, try a complementary product, or convert from a one-time buyer to a subscriber. And they're using that intelligence to drive thousands in incremental revenue.

That's why we partnered with Klaviyo to create our new Email Marketing Play-by-Playbook. It's a deep dive into how six industry-leading brands use data-driven email flows to turn customer behavior into predictable revenue streams.

Today, we're giving you an exclusive preview of how one brand transformed their email marketing results.

How Salt & Stone drives 32% of their retention revenue with cross-sell emails

Salt & Stone, the premium personal care brand founded by former professional athlete Nima Jalali, faced a common challenge: encouraging one-time customers to return and explore their broader product line. With everything from deodorants to body mist to candles, they needed a way to guide customers to complementary products that would enhance their daily routines.

The solution? A strategic Cross-Sell email flow that reaches customers precisely when they're ready to make their next purchase.

Using Repeat's* Cross-Sell Predicted Products Play integrated with Klaviyo, Salt & Stone created a sophisticated flow that:

• Triggers at the optimal moment: The "Primed for Cross-Sell" trigger identifies when customers are most likely to buy again based on their purchase history and behavioral patterns
• Delivers personalized recommendations: Dynamic product suggestions are tailored to each customer's past purchases and preferences
• Reduces friction: Customers are directed to a personalized Repeat Cart pre-populated with complementary products they're most likely to purchase

The flow even includes conditional splits based on whether customers' predictions include specific product categories like Body Wash or Body Mist, ensuring the messaging and recommendations feel perfectly relevant.

The results speak for themselves:

• 32% of Salt & Stone's Repeat-attributed revenue comes from their Cross-Sell email flows
• 49.3% average open rate—significantly exceeding Klaviyo's benchmark for excellent performance
• Automated, data-driven recommendations that require minimal manual effort from their team

What makes this approach so effective is the combination of precise timing and personalization. Instead of sending generic "you might also like" emails, Salt & Stone reaches customers when they're naturally inclined to purchase and shows them exactly what they're most likely to want.
